R&D Report 1966-33 : The transmission of television signals in a narrow bandwidth using frequency modulation W. Wharton, R.E. Davies, P.H.C. Legate The use of frequency modulation for the transmission of television signals through a fused-quartz ultrasonic delay gives a high degree of gain stability and relatively low impairment due to spurious echoes. However the bandwidth available in fused quartz delays of 1 ms delay and above is limited and may be less than twice the highest video modulating...

R&D Report 1961-07 : Crystal-diode modulators for the frequency range 10-1000 Mc/s. G.J. Phillips, R.G. Manton This report describes the development of low-power balanced diode modulators suitable for amplitude modulation by television or sound signals of a carrier in the frequency range 10-1000 Mc/s. From an original model, built in 1954, two later models have been developed having better performance in regard to the insertion loss at the carrier frequency, and uniformity of modulation response...
